Lake Mary police said they confronted Zimmerman, who admitted to exchanging words with the other man.

The 30-year-old Zimmerman was acquitted of murder last July in the February 2012 shooting death of 17-year-old Trayvon Martin.

Zimmerman has since been charged in September 2013 in a domestic violence incident involving his estranged wife and her family, and then again in November in another domestic violence case involving his girlfriend.

She accused him of pointing a shotgun at her, but she later changed her story and asked for the charges to be dropped.

Police questioned him in July after officers spotted him in a truck parked after-hours outside a gun shop, where he claimed to work as an unpaid security guard.

The store manager denied Zimmerman worked there, but he was not charged in the incident.
